ford, England, have invented certain new and useful Improved Machines tor .lleeling Boots or Shoes, of which the following is a specification.

scale, el the upper portion ol' the post, the section heilig taken on the line 7 8 ot Fig. o.

The expanding post, which constitutes the subject ot the present invention, I use with a screw or equivalent press, which has a tollower for pressing upon the heel that is in.-

tended to be attached to the boot or shoe.

I will ii rsi. state tllattliis invention has been l patented to me as follows: ln lnglant'l, December 1l, 18823, No. 5,707; .l `ranee, January 12, 1884, No; 159,080; Germany, January 22, 1884, No. 28,781; Spain, .lune 2U, 1881, No. 4,048, Austria-Hungary, October 27, 1884, No. 27,014; Belgium, March 11, 1884, No. (34,174, and Italy, April 2f), 1884, Vol. 32), No. lltl.

The object ot' this invention is to provide a. device by which the heels of boots or shoes may be nailed on troni the inside, irrespective of the size of such boots or shoes. To this end I construct a laterallyexpanding post i'or the support ot the boot or shoe to be heeled, and 1 provide a series of nail-drivers which have an inclination inward fortorcing up nails from inclined receivers formed in the upper part ofthe post, such nails passing through the insole of the boot into the heel, while that is held in place by the downward pressure of a press follower. The post is composed of two parts connected together by a vertical hinge and capable ot' being opened out, that the top of the post may fit the inner contour Ot the heel part of the boot by the insertion of an adjustable wedge. The drivers are moved upward by means of an eccentric, and they are caused to force upward the nails for securing the heel to the boot.

In the drawings, l1`igure 1 is a back elevation ot the expanding'post, showing also the means for working the nail-drivers. Fig. 2 is an elevation at right angles to Fig. 1, onehalf ot the post being removed. Fig. 3 is a front elevation ol. the lower part of the post, showing the means for Opening the same, its base-plate and supportingguide being drawn in section. Fig. 4 is a plan of the top plates of the post. Figs. 5, (i, and 7 are sectional plans on the lines l. and 2, 23 and 4, and 5 and 6, respectively, of Fig. 1; and Fig. 8 is a sectional elevation,

drawn on an enlarged A, Figs. '1, 2, and 23,is the bed of this press,4

which maybe supported on standards or their equivalent. 1t is provided with guides to receive the base-plate 1l, which carries the post and permits oi its being slid under and away from the plunger of the press. Standing up from this bed-plate B is a vertical rod, which forms the main hinge-pin for the expanding post. lhe bed-plate A is slotted below the base-plate 13 and this plate also is, Afor the same reason, slotted-namely, to allow of the rods by which the drivers are actuated passing through the plates and being free to move toward and from each other.

1) is an eccentric keyed to a horizontal shaft, D', which turns in bearings below the bedplate A. Resting upon the periphery of this eccentric D is a iianged pressureplate, D2, which is free to slide, under the action of the eccentric, in vertical guides fixed to the under side of the bed-plate A.

The expanding post is formed of two castings, E E', which are hollowed out on their inner faces, as shownbest in the elevation, Fig. 2, and in the sectional plan at Fig. (i.

These castings E 1C' interlock at their rear like a butt-hinge, and the interlocking parts are drilled vertically to .receive the supporting hinge-pin C and a second pin, c, which lat ter is made hollow, for a purpose to be presently described. Fitted to the top of this divided post are two steel plates, e e', shaped to correspond generally with the interior of the boot or shoe at the heel. These plat-es are hinged together in the line of the axis of the hinge-pin C by means of the tubular pin c, which passes down through their over and under lying parts into and through the hingepin holes formed in the upper part of the post. The plates e e are rabbeted at their lapping parts, so as to provide a flush surface for the top of the post, and the hollow hinge-pin c passes down to a hollow in the post, in which the drivers e2 e2 e2 are situate. One of these drivers is situated immediately below the hollow hinge-pin c Yand serves, like the other drivers, to support a nail which is deposited therein ready to be forced into the work. Through the plates e e and through the upper and solid part of the halves ot' the post other holes are drilled with an inclination inward to receive nails, and below these holes corresponding drivers are provided for supporting the nails and insuring their lentrance into the work. The drivers are mounted loosely on and carried by a pair of cross-heads,

' c3 e3, which are themselves carried by rods e4,

that rest on the pressure-plate D2. The rise and fall, therefore, of this plate gives the requisite movement to the drivers for forcing the nails out of the solid portions of the post into the work. Rotary motion is communicated to the eccentric D for the purpose of lifting the pressureplate D2, and through it the drivers e?, by a treadle or other suitable mechanism connected with the eccentric-shaft D.

In front of the post, and immediately oppo-V site the vertical opening therein between the hinged pieces E E', stands a wedge, f, which is carried by a sliding bar, F, mounted in guides on the base-plate B. The lower and front part of the post is we dge-shaped in cross'- section, and is embraced by two prongs,f, also carried by the sliding bar F, and inclining inward to correspond to the inclination of the wedge-shaped surfaces on the exterior of the divided post. The object ot' this arrangement is to insure not merely the opening' or expansion of the post as the wedge f is ad- Y vanced, but also the closing of the post as the sliding bar F is drawn backward. The action of the instrument for operating the post will be readily understood on inspecting' the detached views, Figs. 3 and 7. The sliding bar F is moved to and fro in its guides by means of a hand-lever, F', pivoted on the base-plate B and connected to the bar F by a link, f2.

f3 is a clamping-screw, which passes up through the slot in the plate B and through a hole in the bar F, to receive a fly-nut for holding the wedge f in its set position.

In carrying out the operation of nailing on the boot-heel the workman first inserts the nails head downward in the post and then places the boot, sole upward, upon the post, the toe of the boot pointing toward him, while standing in front of the press. At this time the base-plate B will be drawn toward the workman and in front of the press-follower. IIe next expands the post by advancing' the wedge f and securing' it in position, as already explained. In doing' this the workman centers the work upon the post and holds it firmly thereon. This being accomplished, he pushes back the plate B until the post is immediately under the press-follower, and having placed the heel in position upon the boot he brings down upon it the follower, and thereby holds the heel firmly to the boot ready to receive the ascending nails.

The rise of the nails through the insole and into the applied heel is then effected by the workman applying his foot to a treadle or equivalent mechanism, and thereby causing the rotation of the eccentric D. The drivers will then rise, force the nails out of their receptacles and bury them in the work, the inclination of the holes in the post serving to guide the nails properly intothe heel7 which, when tapered, needs a considerable divergence of the nails from the vertical line to insure their bedding properly in the heel. Then the nailing is completed, the workman, slipping' his foot from the treadle while the smallest radius of the eccentric is presented to the pressure-plate, will stop the action of the eccentric, the pressure-plate remaining in its lowest position. In order to iit the post to receive and properly center a boot of large size, it is only necessary to advance the wedge f, and thereby increase the lateral expansion of the post. To effect the lateral contraction of the post to suit the smaller sizes of boots and shoes, the wedge f is to be drawn back, when the inclined prongs f will, by their pressure against the sides of the post, contract it laterally to the desired extent, the clamping-screw being' iirst slaekened to provide for such adjustment.

Having now particularly described and as certained the nature of my invent-ion, I declare that what I claim isl. In a boot or shoe nailing machine, the combination of a laterally-expanding post for supporting' and centering' the work, with receptacles at top for receiving' the nails, and a set of drivers for supporting the nails in their receptacles, and means for thrusting' up the nail-drivers to press the nails into the work, as and for the purpose above set forth.

2. In a boot or shoe nailing machine, the combination, with a laterally-expanding' post, of a presser 'plate, rods, as e4, drivers for thrusting the nails into work carried by the post, and an eccentric for raising' the drivers operating upon the presser-plate and said rods, substantially as specied.

3. In a boot or shoe nailing machine, the combination, with an expanding' post formed with nail-receptacles inclining inward, of naildrivers loosely attached to cross-heads carried by rods that are actuated by averticallysliding support, as and for the purposel above described. e
